Carb been cleaned? Valves adjusted to spec? how about the air filter?

wardog76 · Apr 16, 2011

carb looks pretty damn clean, valves unknown only had the warrior a couple months and have been adding parts to run better and air filter looks decent

Alright Id start by getting the valve lash adjusted to spec, dont have the info at hand but you can find it in the downloadable manual in tutorials. Then we'll go from there, I've heard of some running like **** cause the valves arnt opening all the way. You having to use the choke, tells me its a air/fuel issue some where.

ya im just not sure where yet not sure where else to look

1998yamahawarrior · Apr 16, 2011

Yep know how that feels, just do step by step of the run down stuff. Make sure if the valves are ajdusted and then we'll go from there.

see its not a tick its a small knock..... knock kncok then normal dosnt sound like valves to me but not sure

Dont know what the knock is, but it could be something to do with how its running. You should also check your timing.

where is the idle screw on the carb

wardog76 · Apr 17, 2011

also its a minuku carb. is that stock or aftermarket?

elwood · Apr 17, 2011

it is bu the bowl, the screw points downward and has a spring on it to hold it where you turn it. You can turn it by hand from the left side of the quad
